These were the most common type for many years. The body of the generator is shaped somewhat like a bottle, with the drive wheel forming the bottle cap. The drive wheel leans against the sidewall of the tire (sometimes upon a special “generator drive track”) and spins the generator’s main shaft. Inside the body, the shaft rotates the magnets. The image if of a modern Busch & Müller tire-driven generator. | These were the most common type for many years.

They usually have more drag than other designs. They tend to slip in heavy rain or snow. There’s usually some noise. Tire sidewall wear can be a concern with lightweight tires. The generator and its mounting must be carefully aligned with the bike wheel to minimize drag and wear. If the wheel is badly out of true, the generator may slip at that point. Brackets usually clamp to the fork or frame, and may not be advisable with carbon fiber. Bottom-bracket generatorThe generator and mounting clamps are very visible, and some object to the appearance. | They usually have more drag than other designs.
